- Energy efficiency: Inverter or Energy Star certified units offer better long-term savings. Compare CEER ratings and expected energy usage.
- Control options: Smart app, voice control, and remote operation add convenience for daily use and scheduling.
- Installation and portability: Window units stay fixed; portable units provide flexibility but may be less efficient and noisier.
- Maintenance: Check filter accessibility and ease of cleaning to maintain performance and efficiency.
